No one at my house is in them yet... but can I ask what a brown edge is? And FSOT, TTs and GMD?

Haha, sorry we cloth diaperers (CDers!) Online love our acronyms brown edge are the Green Mountain Diaper workhorse fitteds in size large (they indicate sizes by edge stitching color, as on their prefolds too). TT is Tinkle Traps, a work at home mom's shop, she makes a certain kind of fitted out of prefolds. GMD is Green Mountain Diapers, a major CDing company that sells high quality, cotton focused, cloth diapering products. FSOT is For Sale or Trade, various places online (including our slow one here) provide places for swapping or buy/selling used cloth diapers.
